What is the standard of clean workshop? What is the standard of clean workshop?

1. Dust-free workshop refers to controlling the pressure, humidity and temperature in the air at certain indexes, so that the space environment can meet certain production conditions. Dust-free workshop is divided into different standards according to the cleanliness level, and the cleanliness standards of different cleanliness levels are as follows:

2. Grade 10: 0. 1um concentration ≤ 10, 0.2um concentration ≤2. This level is a high-grade purification project, which is suitable for precision and microelectronics technology industries.

3. 100 grade: 0. 1um concentration ≤ 100, 0.2um concentration ≤24, 0.3um concentration ≤ 10, 0.5um concentration ≤4, which is a common grade and is applied to aseptic manufacturing in pharmaceutical industry.

4. Grade 1000: 0. 1um concentration ≤ 1000, 0.2um concentration ≤237, 0.3um concentration ≤ 102, 0.5um concentration ≤35,1.0um. This level is suitable for making miniature models.

5. Grade 10000: 0. 1um concentration ≤ 10000, 0.2um concentration ≤2370, 0.3um concentration ≤ 1020, 0.5um concentration ≤352,10.

6. Grade 100000: 0. 1um concentration ≤ 10000, 0.2um concentration ≤23700, 0.3um concentration ≤ 10200, 0.5um concentration ≤ 3520,65438.

7. Grade 1000000: 0. 1um concentration ≤ 100000, 0.2um concentration ≤237000, 0.3um concentration ≤ 102000, 0.5um concentration ≤35200,/.
